The Rajamandala (or Rāja-maṇḍala meaning "circle of kings";[1]मण्डल, maṇḍala is a Sanskrit word that means "circle") was formulated by the Indian author Chanakya (Kautilya) in his work on politics, the Arthashastra (written between 4th century BCE and 2nd century CE). It describes circles of friendly and enemy states surrounding the king's (raja) state.[2][3] Also known as Mandala theory of foreign policy or Mandala theory, the theory has been called as one of Kautilya's most important postulations regarding foreign policy.[4][5][6]
